Dual NO precursors for blood flow, endurance & muscle performance
Nitric Oxide Support Formula - L-Arginine & L-Citrulline
Nitric oxide governs vascular smooth muscle relaxation, the mechanism that determines how freely blood flows through your arteries and capillaries. The most effective way to support nitric oxide production is through the amino acid precursors that feed the pathway most efficiently. Halea Life Nitric Oxide Support Formula combines 400 mg of L-Citrulline DL-Malate, 350 mg of L-Arginine Hydrochloride, and 50 mg of L-Arginine Alpha-Ketoglutarate in a formula designed to promote vascular health and circulation backed by real research.*
How to Use
As a dietary supplement, adults take two (2) capsules daily. For best results, take with 6-8 oz (177-237 ml) of water or as directed by a healthcare professional. Do not exceed the recommended dose. Store in a cool, dry place. Keep out of reach of children. Do not use if safety seal is damaged or missing. Pregnant or nursing mothers, children under the age of 18, and individuals with a known medical condition should consult a physician before using this or any dietary supplement.

Why Nitric Oxide Support Formula
Most arginine supplements use a single form. This formula combines three: L-Citrulline DL-Malate for the most efficient plasma arginine elevation, L-Arginine HCl as the direct NOS substrate, and L-Arginine Alpha-Ketoglutarate for energy pathway co-support. Three complementary mechanisms addressing the nitric oxide pathway from different angles, no stimulants, in a vegan cellulose capsule.
What Sets It Apart
- L-Citrulline DL-Malate, more effective at raising plasma arginine than arginine alone due to kidney conversion pathway
- Three-form matrix: Citrulline DL-Malate, Arginine HCl, Arginine Alpha-Ketoglutarate for multi-route NO pathway support
- No caffeine, no stimulants, suitable for any time of day including evening use
- Vegetable capsule (cellulose), suitable for vegetarians and vegans
- 60 capsules per bottle: 30-day supply at 2 capsules per day
- Label claim: Promotes vascular health and circulation*
- Honest everyday pricing, no subscriptions, no promo codes, the price you see is the price, year-round
Who This Is For
Nitric oxide supports endothelial function and smooth muscle relaxation in blood vessel walls, the mechanism that determines healthy blood pressure, peripheral circulation, and blood flow efficiency. This formula addresses the nitric oxide pathway through dietary amino acid precursors.*
Enhanced nitric oxide production supports oxygen and nutrient delivery to working muscles during exercise and accelerates the return of blood flow to normal after exertion. For adults who train regularly, the citrulline-arginine combination is one of the most studied pre-exercise amino acid pairings.*
Healthy endothelial function, the ability of blood vessel walls to produce and respond to nitric oxide, is a foundational aspect of cardiovascular wellness. Daily support of the arginine-to-NO pathway contributes to this foundation as part of a healthy diet and lifestyle.*
No caffeine, no stimulants. Circulation and vascular support comes entirely from L-Citrulline DL-Malate, L-Arginine HCl, and L-Arginine Alpha-Ketoglutarate. Suitable for use at any time of day, including evening and before bed.*
How the Ingredients Work
All three active ingredients are listed with individual doses on the label. Each delivers the same fundamental substrate, arginine for nitric oxide synthesis, through distinct absorption and delivery mechanisms.
L-Citrulline DL-Malate
400 mg per servingL-Citrulline DL-Malate is the most bioavailable oral approach to raising plasma arginine levels. Unlike L-Arginine itself, citrulline bypasses first-pass metabolism in the gut and liver, converting to arginine in the kidneys where it enters systemic circulation more efficiently. Research consistently shows citrulline raises plasma arginine levels more effectively and more sustainably than oral arginine supplementation. DL-Malate is a malic acid salt that supports Krebs cycle energy pathways alongside the amino acid.*
L-Arginine Hydrochloride
350 mg per servingL-Arginine HCl is the direct substrate for nitric oxide synthase (NOS), the enzyme that converts arginine to nitric oxide and citrulline in vascular endothelial cells. At 350 mg, it provides direct arginine alongside the more bioavailable citrulline route. The HCl salt form improves stability and solubility compared to free-form arginine, and the two-route delivery (direct arginine + citrulline-converted arginine) supports more sustained nitric oxide pathway activity.*
L-Arginine Alpha-Ketoglutarate
50 mg per servingL-Arginine Alpha-Ketoglutarate (AAKG) is arginine bound to alpha-ketoglutarate, a Krebs cycle intermediate that supports cellular energy production pathways alongside the arginine delivery. AAKG has a distinct absorption profile from L-Arginine HCl and contributes a third delivery mechanism to the formula’s multi-route arginine matrix.*
L-Citrulline raises plasma L-Arginine levels more effectively than L-Arginine supplementation alone, because it bypasses the first-pass metabolism in the gut and liver that limits how much oral arginine reaches systemic circulation.
